Helm & Crew
Following the removal of the traveller as previously
described, the new mainsheet uses the now common 'split bridle' system; the 8mm
mainsheet has two 4mm 'tails' spliced side-by-side into one end, each of are
attached to either side of the rear deck, more or less level with the rudder
post. A block at the rear end of the boom leads the mainsheet up and forwards
(along the underside of the boom) to the middle of the boat, where a second
block on the boom sends it down to the centre-jammer mounted on the aft end of
the centre console.
The purpose of the split bridle is to enable the boom to be
centre-lined without using excessive sheet tension - for this to work however
requires the 4mm bridle ropes to pull right through the aft boom block when the
mainsheet is fully in - I see many boats where the 4mm - 8mm join is below the
block, which prevents the system working properly.
In stronger winds an additional purchase is required, so two
extra blocks are provided to facilitate this; rather than going straight into
the centre-jammer, the mainsheet in this case is led to an extra block on the
console, and then back up to an extra block on the boom, after which it goes
back down through the jammer as before.
Two further tweaks are added to the mainsheet system, both
of which are designed to prevent the mainsheet catching things when it goes
slack during tacks and gybes. The first of these tweaks is a length of 4mm
shockcord led from each corner of the transom to the rear end of the tiller,
thus preventing the mainsheet getting caught around this point. The second
tweak is to run a sailcloth 'sleeve' under the boom to prevent the mainsheet
hanging down and decapitating the helm at inopportune moments.
Main sheet jammer.
Sheet is rigged for light winds. The second block on the boom and the small
block mounted in front of the jammer are used to add a 2:1 for heavier
